Ubonelelo lweFactory Umgangatho oPhezulu weSodium Acetate Supplier CAS 127-09-3

Iinkcukacha zemveliso

MF: C2H3NaO2
MW: 82.03379
CAS: 127-09-3

I-1.I-acetate ye-sodium yaziwa nangokuthi i-acetate ye-sodium.Ayinambala, ayinavumba, i-monoclinic ecacileyo ikholamu yekristale, okanye umgubo omhlophe wekristale.

2.Kwimveliso yokutya, isetyenziswa njengesithinteli kwisinongo kunye nesigcini senyama.Lawula into encangathi ebangelwa ngumngundo kwimveliso yesonka kwaye uyisebenzise ekugcinweni okuziinkozo kunye nomxholo ophezulu wamanzi;Le mveliso ingasetyenziswa njengoshicilelo lwelaphu chemicalbook ukudaya encedisayo (mordant), buffer kushishino lweefoto, reagent imichiza kunye intermediate pharmaceutical;Isenokusetyenziswa njengemathiriyeli ekrwada yokwenziwa kweemveliso zemichiza ephilayo, njenge-furan acrylic acid, i-acetate esters, i-chloroacetic acid, i-acetic anhydride kunye ne-cinnamic acid.

I-3.I-crystal engenambala kunye ne-odorless, enokuthi ibe yimozulu kwaye ivuthe emoyeni.Inyibilika emanzini nakwi-ether, inyibilika kancinane kwi-ethanol.Indawo yokunyibilika ye-sodium acetate trihydrate yi-58 ℃, ukuxinana kwe-chemicalbook1.45, kunye nendawo yokutshisa okuzenzekelayo yi-607.2 ℃.Susa iimolekyuli ezi-3 zamanzi kwi-123 ℃.Indawo yokunyibilika ye-acetate ye-sodium ene-anhydrous yi-324 ℃, kwaye ubuninzi obusondeleyo yi-1.528.

Isicelo

I-1.Anhydrous sodium acetate ingasetyenziselwa kwi-organic synthesis ye-esterification agents, iziyobisi zezithombe, amayeza, ukuprinta kunye nokudaya i-modants, i-buffers, i-reagents yeekhemikhali, i-preservatives yenyama, i-pigments kunye neminye imiba emininzi, kwaye ingasetyenziselwa ukuvelisa iimveliso zeekhemikhali ezahlukeneyo. njenge-furan propylene chemicalbook enoic acid, i-acetate kunye ne-chloroacetic acid.Njengesithinteli se-seasoning, le mveliso inokuthintela ukujika kombala kwaye inesiphumo esithile sokulwa nokungunda.Isenokusetyenziswa njenge-agent emuncu kwi-sauce yesinongo, ikhaphetshu evundiweyo, imayonnaise, ikeyiki yentlanzi, isoseji, isonka, ikeyiki yerayisi, njl.

I-2.I-acetate ye-sodium idlala indima enkulu ekulungiseni ixabiso le-pH le-sewage kunyango logutyulo.I-acetate ye-sodium yikhemikhali ye-alkaline, enokuthi ifakwe i-hydrolyzed emanzini ukuze yenze i-Oh ion negative, enokuthi i-neutralize i-chemicalbook kunye ne-acidic ions emanzini, njenge-h +, nh4 +.I-hydrolysis reaction formula ye-sodium acetate yile: ch3coo-+h2o= reversible =ch3cooh+oh-.
